Calling setWhere results in firing the addfeature event twice. (seems related to #790)
Example: http://jsbin.com/kiripelipa/edit?html,output

• Browser and version:

Chrome 54

• Version of Leaflet (L.version):

1.0.1

• Version of esri Leaflet (L.esri.VERSION):

Debug this issue and turns out that the problem potentially related to: https://github.com/Esri/esri-leaflet/blob/master/src/Layers/FeatureLayer/FeatureLayer.js#L122-L142

That createLayers & addLayers method fire 'addfeature' event twice and I assume that's the reason the addfeature event triggered twice @jgravois
